Overview

NEWLIFE Powder Metallurgy (PM) Self-Lubricating Bearings are engineered for high-volume mechanical assemblies that demand long-term maintenance-free operation, low friction, and high wear resistance. These bearings are fabricated using in-house PM powders and controlled sintering processes, resulting in a porous structure that retains lubricants such as oil or graphite, enabling continuous self-lubrication throughout service life. The near-net-shape PM approach allows complex geometries with minimal secondary machining, offering cost advantages over traditional bronze or steel bushings that require extensive machining and lubrication grooves.

Compared with conventional machined bearings, PM self-lubricating bearings offer uniform material distribution, superior dimensional accuracy, and predictable porosity, ensuring consistent friction performance and wear characteristics. NEWLIFE leverages proprietary powders and sintering profiles to optimize bearing density, hardness, and lubricant retention, enhancing bearing lifespan and operational reliability under variable loads, speeds, and temperatures. Additionally, the PM process reduces material waste and energy consumption, making it ideal for high-volume automotive, appliance, and industrial applications.

These bearings are available in a wide variety of forms: sleeve, flange, thrust, or customized geometries, enabling integration into pumps, motors, gearboxes, and automation equipment. Their self-lubricating properties reduce maintenance costs and downtime while maintaining smooth operation and low noise. Surface treatments or impregnated coatings can further improve corrosion resistance and wear performance in demanding environments.

NEWLIFE PM self-lubricating bearings demonstrate the advantages of modern powder metallurgy over traditional fabrication: precise dimensional control, cost-effective scalability, predictable mechanical and tribological performance, and the elimination of external lubrication in many cases. This combination of features makes them highly suitable for applications where reliability, efficiency, and reduced maintenance are paramount.
